T" all lwhom t 'may concern:

Be it known lthat I, WILIJAMBELLMAR, a citizen ofthe UnitedStates, and aresi-,. dent of the city of Yew York, Astoria, borough of Queens, inthecounty of Queens and State of New York, have invented a new and ImprovedPlush-Loom-Cutter Stop, of which the following is a full, clear, andexact description. 1 i n This invention relates to stop motions forlooms and particularly for plush looms, and has for an'object to providean improvedy construction wherein the cutter yused in thev loom 'mayautomatically stop the loom when the operating mechanism therefor vfailsto properly function. l i

Another object ofthe inventionis to pro-l videkan improved connectionbetween the f cutter of a plushy loom and the regular stop mechanismthereof so that when the mecha? nism for moving the cutter failstooperate, the machine will be automatically stopped by its regular stopmechanism. f

A .stillk further objecty more specifically is to provide an improvedarrangement for stopping a plush loom when the operating rope of thecutter breaks, the-arrangement being such as to require no change in thestop motion mechanism of the loom or any change in the construction ofthe rope opera-ting mechanism of the cutter.

In the accompanying drawings- F igureY 1 is a fragmentary front view ofa plush loom showing a' cutter mechanism and a stop motion mechanismembodying the invention associated therewith;

4 Fig. 2 is a fragmentary side view of the loom shown in Figpl, with theconnecting stop motion mechanism embodying the invention shown appliedthereto; a

Fig. 3 isv a fragmentary diagrammatic view illustrating how the stopmotion mechanism fof the machine operates ;l

Fig. 4 is a fragmentary-rear view of vpart of the stop ymechanism shownin Fig. 2.

`Referring to the accompanying drawings by numeral, 1 indicates ltheframe of a plush loom, which frame supports the various mechanismsnecessary to complete the loom.

As the particular. mechanism lof the loom forms no part of the presentinvention, the

same has been omitted principally from the f drawings and will not bedescribed.

In connection with theloom, ya cutter 21s 192s. seria1i0'o.e41,474. i

usedto cut the pile during the operation ofv themachine. This cuttermaybe of any type and is operated or moved back and forth by a cable 3,which passesover suitable guiding pulleys 4 and 5,'as'well as .over anumber of other pulleys 6 supported in any suitable manner by the framel, whereby the cable is permitted a free backand-forth movement and alsowhereby proper mechanism may be connected therewith for `causing' yaproper back-and-forth rmovement thereof. This cable, the pulleys,

mechanism ofthe loom and is connected up in such a way as to functionwithout` disturbing thestopping of the loom bythe automatic means in theusual manner.

As indicated in Fig. 1 the pulley wheel 7 rests vagainst the cable 3 andpreferably presses the same outwardly'by reason of its fweightp Thispulley is pivotally mounted `in any suitablemanner upon a bar 8pivotally supported asat 9 on a fixed stationary bracket l() carried inany suitable manner by the frame 1. The bar 8 is provided with a pin 11which projects through a slot or elongated aperture 12 formed in the endof a crank arm 13, which crank arm is bent fat 14 ork at this pointformed integral with a rearwardlyfextending shaft 15. yThe shaft 15 iscarried by any desired number vof supporting brackets 16, anda-t therear end is provided with an upstanding arm 17 lbent at y18 to form abar 19 which supports a U-shaped connector 20, the bar 19 beingconnected to the connector 20 in any desiredl manner. The connector 20is one of a number of-similar connectors used in the system shown inFig. 3, (except that it isconneeted with bar 19) whichsystem is awell-known system now commonly used on plush looms.

This system of stop-motion consists essentially` in providing insulatedcontact plates 21 and 22, said contact plates being straddled Aby therespective connectors 20, and said connectors being supported in anysuitable manner by the threads of the machine except the one connectedto the bar 19 so that when any thread breaks, that particular connectorwill drop under the action of gravity and assume the position shown inFig. 3. This will connect the plates 21 and 22 so that current will fiowthrough these two plates from the source 23 and also through therespective wires 24, 25 and 2G, so as to energize the electromagnet 27.wWhen the electromagnet 27 is energized, it will move the armature 2S sothat the errtension 29 will move away from the contact post 30. rlhisbreaks the circuit of the motor 31, which motor is connected up fordriving the loom. The particular connector 20 secured to the bar or rod19 is swung back and forth 'by said bar instead of being dropped bygravity, and said bar through the shaft 15 and associated parts, ismoved under the action of the arm 8. rlhis arm is swung downwardly tothe dotted line position shown in Fig. l, by the pulley 7 acting undergravity when the cord or cable 3 breaks. As the pulley 7 is pivotallymounted on the supporting bar or arm S, it will freely rotate with aback-and-forth Inovement as the cable 3 reciprocates. By reason of thisconstruction and arrangement, the cutter 2 may freely reciprocate toperform its usual function without molcsting the stop mechanism, whichstop mechanism is caused to function when the cable 3 breaks and permitsthe pulley to swing downwardly so that shaft 15 will be rocked and theconnector secured to bar 19 moved downwardly to the position shown inFigure 3.

What I cla-im is 1. The combination with a plush loom provided with acutting mechanism formed with a cable or ligament and a stop motion forthe loom provided with a number of connectors for closing the electricalcircuit used in stopping` the loom, of a member normally supported bysaid ligament, and a plurality of means connected with said member' andoperated and with one of said connectors thereby when said ligamentpermits said member to move downwardly, said downward movement resultingin a suflicient operation for said members to move one of saidconnectors into operative position.

2. The combination with a loom provided with a stop motion mechanismincludingl a substantially li-shaped' connectorl adapted to be inoperative position when lowered and in inoperative position when raised,said loom also being provided with a cutting mechanism constructed witha cable, of means actuated when said cable breaks for moving one of saidconnectors to an operated position vfor stopping said loom, said meansincluding` a pivotallj).v mounted arm, a wheel carried by said arm andnormally resting` against said cable, a rock shaft actuated by aid armwhen the same moves from a given position, and means actuated by saidrock shaft for moving one of the connectors to an operative positionwhereby the loom will be stopped when said cable is broken.
